Updates
Added by ESS 09/10/1025 Schools should ensure that ethnicity and disability information is recorded for workforce members within 100 calendar days of them joining the school
During our suppliers meeting with the DfE on 15/07/2025, the DfE made it clear that schools should be recording both ethnicity and disability information for their workforce members within 100 days (3 months) of those workforce members having joined the school.
The ethnicity aspect of this requirement is unlikely to need much implementing for most schools, but the new disability field was only introduced as blank to SIMS by the SIMS Summer Release 2025 and will need to be fully implemented as soon as possible and before the School Workforce Census 2025 is uploaded to the DfE via COLLECT.
Ethnicity
Acceptable: Any of the Ethnicity lookups, including ‘Did not wish to be recorded’, except for ‘Not obtained’.
Unacceptable: Blank or ‘Not obtained’.
Disability
Acceptable: Any of the Disability lookups, including ‘Refused’, except for ‘Information not yet obtained’.
Unacceptable: Blank or ‘information not yet obtained’.

| Rule number | Validation Check | Error Messages |
| 4221Q | Where <SchoolArrivalDate> present, and <ReferenceDate> minus <SchoolArrivalDate> greater than 100 days, then <Ethnicity> should not be equal to ‘NOBT’ | Please check: Staff member started more than 3 months previously but Ethnicity has not been obtained. Staff members can refuse to provide the information, but it should be asked for. Refusal should be recorded as ‘Refused’ (REFU), not as ‘Information not yet obtained’ (NOBT). |
| 4225 | <Disability> must be provided and field format and/or allowed values must match associated CBDS entry | Disability is missing or invalid. This data is important to improve outcomes and opportunities for disabled people and should be fully reported. |
| 4226Q | Where <SchoolArrivalDate> present, and <ReferenceDate> minus <SchoolArrivalDate> greater than 100 days, then <Disability> should not be equal to ‘NOBT’ | Please check: Staff member started more than 3 months previously but Disability Status has not been obtained. Staff members can refuse to provide the information, but it should be asked for. Refusal should be recorded as ‘Refused’ (REFU), not as ‘Information not yet obtained’ (NOBT). |
Please note
There are two ethnicity category codes referred to above that have slightly different descriptions in CBDS compared to SIMS. However, we don’t expect this to cause confusion.
| Staff Ethnicity Category Code | CBDS Description | SIMS Description |
| NOBT | Information not yet obtained | NOBT – Not Obtained |
| REFU | Refused | REFU – Did not wish to be recorded |

Added by ESS 29/07/2025 Initial version of the DfE validations and SIMS solutions Excel workbook
Version 2025.1.0 of the workbook is available from our Statutory Returns Downloads page. This initial version is based on version 2025.1.0 of the DfE validation workbook for School Workforce Census 2025 and the SIMS solutions file provided by Fileset 3101. You will find that several new DfE validations don’t yet have a SIMS solution, but those missing solutions will be put in place by Fileset 3102.

Added by ESS 11/07/2025 Disability for staff who have left the school
As you probably know, staff who have left the school may be included in the return depending on when they left and what type of work they did while employed at the school. This means that some staff who have left the school may be included in the return, with an indication of how they see themselves in terms of disability to be included. The DfE validation will apply the same rules for the disability of staff who have left as it does for staff who are still employed at the school.
However, the DfE also recognises that schools may not be able to obtain information regarding how staff sees themselves in terms of disability when they are no longer employed at the school and will therefore look into allowing schools to add a note on COLLECT to explain why it has not been possible for the school to collect this disability information for a member of staff that has left.
Added by ESS 07/07/2025 Staff disability related information
As you probably know, there is now legislation regarding employers reporting disability where they have 250 or more employees. With this in mind, DfE is adding validation to its collection of disability data in School Workforce Census 2025.
For this purpose, disability is defined in terms of how the members of staff see themselves in terms of disability rather than allocation of a Disability Number.
The data to be reported in SWC 2025 will be restricted to the following CBDS items, with validation checking that NOBT (Information not yet obtained) is not reported for staff who have been employed for six months or more.
| Disability Code | Description |
| YES | Yes |
| NO | No |
| REFU | Refused |
| NOBT | Information not yet obtained |
The current ‘Are day to day activities substantially affected by physical or mental impairment’ field in Personal Information panel of Focus | Person | Staff will be retained. However, it will not be reported in School Workforce Census 2025, as limitations implied by the field name are no longer relevant for the census.
Are day to day activities substantially affected by physical or mental impairment
| Not disabled |
| Disabled |
| Not known |
| Declined to specify |
We have provided a new ‘Disability’ field in the Personal Information panel of Focus | Person | staff, and schools will need to add an appropriate value to avoid a validation error in the census. ‘Disability’ values will not be defaulted.
Disability
| Yes |
| No |
| Refused |
| Information not yet obtained |
